Adding a Spring dependency into a gradle task - maven

Question

I want to add a special gradle task on my machine as an init script. The script is in ~/.gradle/init.d. Let's call it servertest.gradle. It looks like this:
import org.springframework.http.MediaType
allprojects {
task servertest {
doLast {
MediaType.parseMediaType("application/json")
}
}
}
I can run the task, but it says this:
> startup failed:
initialization script '/home/user1/.gradle/init.d/servertest.gradle': 1: unable to resolve class org.springframework.http.MediaType
# line 1, column 1.
import org.springframework.http.MediaType
^

Of course, what I really need to do is more complicated than this, but this is a simplified example of using a Spring Library in a Gradle Task.
How do I import the spring libraries into a task?

Answer 1

Basically, dependency missing.
The MediaType class is in spring-web library.
Here is how the gradle file with dependency should look like:
import org.springframework.http.MediaType
initscript {
repositories {
mavenCentral()
}
dependencies {
// https://mvnrepository.com/artifact/org.springframework/spring-web
classpath group: 'org.springframework', name: 'spring-web', version: '4.3.11.RELEASE'
}
}
allprojects {
task servertest {
doLast {
MediaType.parseMediaType("application/json")
}
}
}
